What was the Black Death?

Did bubonic plague really cause the Black Death? This was one of the questions tackled in BBC TV’s Decoding Disaster, which went out under the Timewatch banner.

What is certain is that the epidemic was one of the greatest, if not the greatest, disaster in history, killing perhaps 75 million people in Europe and Asia from 1346 to 1353 – 30 to 40 per cent of the population. The conventional explanation is that it was bubonic plague, carried by the fleas of the black rat, along with pneumonic and septicaemic plague which could be transmitted from person to person.

Sceptics, though, have suggested there were just not enough rats to spread the disease on the scale that happened, so other ideas have been suggested – notably anthrax or some kind of haemorrhagic plague, like Ebola. Others maintain that with a death toll on this scale, a number of different diseases must have been raging at the same time.

At the time, top academics at Paris University came up with their own explanation: a triple conjunction of Saturn, Jupiter and Mars in the 40th degree of Aquarius on 20 March 1345, but they were humble enough to acknowledge that some things were ‘hidden from even the most highly trained intellects.’

Plague hits Madagascar

Plague has struck Madagascar again. More than 40 people in five districts have been killed by the bubonic version, spread by rats’ fleas, while two have died from the even more lethal pneumonic type, which is spread from person to person and can kill in 24 hours.

Last year, the island suffered more deaths from the disease than any other country – 60. There has been a programme to exterminate rats and fleas in Madagascar’s prisons, but the Red Cross warned in October that there was danger of an epidemic, following a fall in living standards since a coup in 2009.

Health officials have gone to the areas affected to investigate, but the local WHO office says medicines are in short supply.

Most, though not all, scientists believe bubonic and pneumonic plague caused the world’s deadliest epidemic – the Black Death, which killed perhaps a third of Europe’s population and countless more in Asia from about 1334 to 1351.
